Abstract: An aerial ropeway hazard sensing system including a radar sensing unit mounted at a position along a ropeway that generates radar data representative of predetermined ropeway conditions proximate the radar sensing unit, and a processor that analyzes data from the radar sensing unit to detect predetermined hazard conditions and to generate a hazard detection signal indicative thereof. A method of performing an aerial ropeway safety function comprises using radar to detect a hazard condition and generating a hazard detection signal in response thereto; generating a control signal in response to the hazard detection signal; and initiating a safety with the control signal.

Abstract: Drive sheaves are disclosed herein. An embodiment of a drive sheave includes a tire portion wherein the tire portion comprises an inner circumferential surface and an outer circumferential surface. The tire portion also includes a first surface extending between the inner circumferential surface and the outer circumferential surface and a second surface extending between the inner circumferential surface and the outer circumferential surface, the second surface being oppositely disposed relative to the first surface. At least one hole in the tire portion extends between the first surface and the second surface.

Abstract: A ropeway may include at least one cable. A first sensor and a second sensor may be provided. The second sensor may be located between the first sensor and the cable. Related methodology is also disclosed.

Abstract: A drive sheave equipped with a deformable tire is disclosed herein. An embodiment of the drive sheave comprises a tire portion wherein the tire portion comprises an inner circumferential surface and an outer circumferential surface. The tire portion also comprises a first surface extending between the inner circumferential surface and the outer circumferential surface. In addition, the tire portion comprises a second surface extending between the inner circumferential surface and the outer circumferential surface, wherein the second surface is oppositely disposed relative to the first surface. At least one opening in the tire portion extends between the first surface and the second surface.

Abstract: A damage indicator for indicating potential damage to a sensor.

Abstract: An aerial ropeway wherein oppositely located first and second sheave trains are supported on a crossarm wherein first and second sheave train supporting apparatus are pivotally mounted at fixed spaced apart locations on the crossarm and the first and second sheave train supporting apparatus are each pivotally connected to an elongated member extending therebetween.

Abstract: A sheave support system for supporting the sheaves of a multiple sheave assembly relative to a support structure, such as a ski lift tower, which comprises at least two sheave members rotatably mounted on the sheave assembly in spaced parallel relationship for supporting the ski lift cable; at least one main support shaft for movably supporting the sheave assembly relative to the ski lift tower; at least two intermediate support arms mounted on the main support shaft; and at least two intermediate support shafts mounted on opposite ends of the intermediate support arm for rotatably supporting the sheave. The support shaft means comprises a support shaft, a hub member mounted circumjacent the support shaft, and an elastic bushing device mounted between the support shaft and the hub member for connecting the hub member to the shaft member while enabling limited relative rotative movement therebetween of less than approximately 15 degrees and also limiting transmission of vibration therebetween.
